Embodiment Construction

[0051] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0052] Since the users of the SMPD model are mainly model researchers and population data users, the needs of such users have been described in detail above. Based on the needs of such users, the system design should consider the following special requirements:

[0053] First, the system should include a metadata management module to uniformly and effectively manage the metadata information of the entire system, and provide standard documents for future system upgrades and system integration;

[0054] Second, the model calculation module should have the characteristics of structure and scalability, so that it is easy to modify and add new models;

[0055] Third, in order to ensure that the system output results are accept...

Abstract

The invention discloses a population spatial distribution numerical simulation system, comprising: a data input unit for carrying out the pre-treatment of the input original data received from the outside and outputting the data to a database management unit; the database management unit for storing and managing the input data of the data input unit; a model base management unit for storing and managing data models; a model calculation unit for carrying out the model calculation of the data and outputting the result to an error analysis unit, an inquiry statistical unit or a chart output unit; the error analysis unit for carrying out the error analysis of the data and the calculation result and outputting the result to the chart output unit; the inquiry statistical unit for carrying out the inquiry statistics of the data and the calculation result and outputting the inquiry statistical result to the chart output unit; and the chart output unit for adopting a map mode or a statistical chart mode to display or print and output the processing result. The population spatial distribution numerical simulation system can solve the problems of maintenance, management, error analysis, etc. of SMPD models.

Description

technical field [0001] The present invention relates to the fields of geographic information system technology, database management technology and model library management technology, and in particular to a numerical simulation system of population spatial distribution based on the above three technologies. Background technique [0002] The Surface Model of Population Spatial Distribution (SMPD) is a complex system that integrates multiple data sources and multiple spatial scales. Through inversion and prediction, the model calculates the population density according to uniformly distributed and regular-sized grid cells, which breaks through the traditional method of calculating population density based on administrative district boundaries, enriches the methods for obtaining population density indicators, and improves population density. The accuracy and scope of application of the indicators. [0003] The SMPD model is not only perfect in theory and uses more original dat...
